Antoine equations can only be used with pure components, not with mixtures. Considering ideal behaviour, the vapor pressure of a mixture would be P = P1*x1 + P2*x2 (Raoult's law), where P1 and P2 are the vapor pressures of the two components and x1 and x2 their molar fractions

How do you calculate actual vapour pressure?
Actual vapor pressure can be calculated using the Antoine equation, which is a function of temperature and constants specific to the substance of interest. The equation is: ln(P) = A - (B / (T + C)), where P is the actual vapor pressure, T is the temperature in Kelvin, and A, B, and C are substance-specific constants.

Antoine coefficients Light Naphtha?
The Antoine coefficients are empirical constants used in the Antoine equation to describe the relationship between vapor pressure and temperature for a given substance. For light naphtha, these coefficients enable the calculation of vapor pressure at various temperatures, which is crucial for processes like distillation and refining in the petrochemical industry. Typically, the coefficients are determined experimentally and can vary based on the specific composition of the naphtha. Generally, light naphtha has a boiling range of about 30°C to 90°C, and its vapor pressure characteristics are essential for safe handling and processing.
